Liverpool suffered their first defeat of their pre-season campaign with a 1-0 loss to Chelsea in their International Champions Cup clash in Los Angeles.

It was a tight contest with very few chances that was settled with a 10th minute goal from Gary Cahill as he headed home a Cesc Fabregas corner.

While conceding from a set-piece is a familiar feeling for Liverpool, it's another familiar feeling on twitter for several Liverpool fans in being dissastisfied with the performance of left-back Alberto Moreno.

Moreno certainly made his mark on the game early on with a poor challenge on Willian in the sixth minute, which saw the Spaniard deservedly booked.

There were times when he seemed to look a threat going forward but did look vulnerable at times, but given there is a lack of competition for the Spaniard in that area, it seems that many are determined to see at least some competition at left-back, or an upgrade altogether.

Here is a selection of what some fans on twitter had to say:

Of course Moreno puts in a full blown challenge on Willian in a friendly.
